At a young age, one tends to have good skin that is radiant. As one gets older, this changes. The skin has been exposed to a lot of factors that can make it look stretched, wrinkled and rough. Some things can help with this transformation or at least slow down the aging process according to a derm doctor.
Factors
Wear sunscreen
UV rays from the sun can cause sun spots, wrinkles, and even skin cancer. It is very important to wear sunscreen even when going out for five minutes. Sunscreen should be applied in areas that are directly exposed to the sun like the face, arms, and chest. Such areas are also the most sensitive to UV rays.
Eat healthy
Being on a healthy diet is essential for the skin. Vegetables and fruits help one have a radiant and smooth skin. They 
are rich in antioxidants that break down cancer-causing free radicals in the body. These free radicals are the ones that cause damage to the skin.
Drink plenty of water
Water helps to flush out toxins in the body. The toxins are the ones that clog the skin and make it appear dull. Even after a night of drinking, one is advised to take a lot of water. Taking a lot of water, the eight glasses in a day makes one appear radiant.
Avoid smoking
Smoking damages the skin because it has very many toxic chemicals. The skin of long term smokers is pale and wrinkled even on young people. It cracks up the lips and makes one look old and distressed.
Apply eye cream
The region around the eye is the most sensitive in the whole body. Application of a good eye cream on a daily basis will help one avoid eye puffiness and the region looking dark. This, in turn, helps the skin to look fresh.
Avoid harsh creams
Some skin creams are harsh for the skin. They contain chemicals that mess up the melanin. Some of those products 
include bleaching products and products that are advertised to even the skin tone. It is, therefore, advisable to consult a dermatologist before using any product that may be harmful to the skin.
The skin is very sensitive, and it can be used to detect if one is healthy or not. Small things like even washing it before sleeping on a daily basis could help it a lot. Therefore, skin care should be taken very seriously.
